FURNACE-LINING FOR MARINE CASINGS.

Specification of Letters Patent.

Patented Sept. 12, 1916.

Application filed February 21, 1916. Serial No. 79,537.

I To all whom it may concern Be it known that I, EDWARD C. MEIER, acitizen of the United States, residing at Phoenixville, in the county ofChester and State of Pennsylvania, have invented cortain new and usefulImprovements in Furtrace-Linings for Marine Casings, of which thefollowing is a specification.

My invention relates to improvements 1n furnace lining for marinecasings, the object of the invention being toprovide animproved-construction and arrangement of fire bricks or blocks withimproved means for securing the same to the casing, so that 'the liningcannot shake loose by reason of the motion and vibrations of the vessel.

A further object is to provide an improved construction of block whichis adapted to be laid like an ordinary brick wall, and v which permitsthe anchoring of the blocks asithey are laid, so that they areeffectually secured to the casing wall.

.With these and other objects in view, the invention consists in certainnovel features of construction and combinations and arrangements ofparts as will be more fully hereinafter described and pointed out in theclaims. I

. In the accompanying drawings: Figure 1 is a fragmentary view inhorizontal section illustrating my improvements. Fig. 2 is a fragmentaryview in vertical section on the 'line 2-2 of Fig. 1, and Fig. 3 is aface view of a fragment of, the lining on a reduced scale.

1 represents a marine casing tothe inner face of which my improved wholeblocks) and half blocks 2 are secured, and a lining 3 of any suitablematerial is preferably interposed between the blocks and the casing 1.Each block 2 and 2 is of fire brick, and is provided in its upper andlower faces with recesses 4. The whole blocks 2 have two recesses intheir upper and lower faces, and the half blocks have single recesses intheir upper and lower faces. is widest at the face of the block adjacentli'nin'g 3, and the side'walls of the recess con ver e to the inner endof the recess where the wall of the recess is rounded as shown at 5. Inthe inner portion of each recess 4,

a socket 6 is provided, and these sockets are sufiiciently spaced fromthe walls of the recess 4 to permit the manipulation of a hook bolt 7 asthe latter is positioned around a dowel pin Each recess 4 The dowel pins8 extend into the alined sockets 6, and are preferably of cast iron orwrought steel, and are of a diameter smaller than the diameter of thesockets so as to re ceive a slushing of fire clay 9 around the 7 'same.It will be noted, particularly by reference to Fig. 2, that the sockets6 in the bottom of the bricks are at least twice the depth of thesockets in' the tops of the bricks,

or in other words, the sockets in the bottoms of the bricks are ofadepth sutiicient to accommodate the entire pin which is essential forrepair work as will be hereinafter described. The hook bolts 7 inrecesses 4 are also embedded in this fire clay 9, and the ends of thehook bolts extend through lining 3 and casing 1, and are nuts 10.

As shown clearly in Fig. 3, the blocks are laid like ordinary bricks,and each block is secured against the casing by bolts, so that there isno possibility of the block workin loose due to the movement of thevesse The slushing of fire clay can be utilized to fill in all spaces,and a tight fireproof Wall can be thus formed in marine casings withoutdanger of working loose. It is to be understood that the apparatus maybe bent or otherwise shaped to register with the openin s in the marinecasing, and while I have shown most of the bolts as straight, it is tobe understood that they may take various positions. To illustrate this,one of the bolts is bent, and var ousangular dispositions may beresorted to with the bolts in order to adapt them tothe ca smo.

While I have shown each pin as provided with a hook bolt, I may dispensewith. some of the hook bolts if found desirahlc. One important featureof my improved construction is that it permits a burnt block to beremoved, and replaced by a new one.

The operation of this repair work is as follows: The brick to be renewedis chopped to pieces, and removed, and all superfluous sloshing isremoved from the surfaces of the bricks and from the sockets 6.- Pinsare then inserted in the sockets 6 in the bottom of the exposed brick inthe wall, and held in place preferably by a thin metal plate. The newbrick is inserted with pins 8 in its bottom sockets, and slid into placeuntil the sockets register, when the pins will fall by gravity intolocking position. I may, of course, resort to other means than ametalsecured by plate for holding the pins against downward movement, and insome cases may merely tighten the hook bolts holding the pins, so as togive suilicient frictional engagement to prevent them from falling, andwhen the new block is in place, slightly release the bolt to allow thepin to fall.

\Vhile I have described my improvements in connection with a marinefurnace, it is of course to be understood that I do not limit myself tothis use, but wish to cover the lining in connection with any furnacewith which it is adapted. I would also have it understood thatthe shapeofthe recesses may be varied, and that the purpose of the widening orflaring shape is to permit the bolts to take any angle necessary forattachment.

Various slight changes might be made in the general form andarra'ngen'ient of parts ,described without departingfrom my inven tion,and hence I do not limit myself to the precise details set forth, butconsider my- "self at liberty to make such changes and alterations asfairly fall within the spirit and scope of the appended claims.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is:

1. A lining of the character described, comprising blocks havingregistering sockets of different depths, a member of greater length thanthe. shortest socket and slidable from one socket to another, saidmember being designed to hold-the blocks together, and a locking deviceadapted to hold the blocks againsta casing, sulistantially as described.

2 A lining of the character described v comprising blocks arranged oneabove the other, each having registering sockets, thesocket of the upperblock being of greater depth than the socket of the lower block, amember of such length as to extend into the upper socket and to movepartly into the lower socket, and a device connected to said member anddesigned "to be secured to a'casing, substantially as described.

3. A lining of the character described, comprising blocks havingrecesses therein and alined sockets, of different depths, intersectingthe recessesf pins of greater length than the short sockets and capableof fitting within the deeper sockets, said pins being adapted to holdthe blbcks against a casing,

substantially as described. 7

4; A lining of the character described, comprising blocks havingrecesses therein and alincd sockets, of different depths, intersectingthe rece. s pins of greater length than the short sockets and capable offitting within the deeper sockets, said pins being designed to projectacross tlie recesses and into the sockets of adjacent blocks, aridindependent book bolts having portions extending around the pins, saidbolts having othew'portions projecting through the recesses and adaptedto be secured to a casing, substantially as described.

A liningof the character described;

-con'1prising. blocks having recesses therein and aiincd sockets, ofdifferent depths, intersecting the recesses, pins of greater length thanthe short sockets and capable of fitting within the deeper sockets, saidpins being designed to project across the recesses and into the socketsofadjaeent blocks, and independent hook bolts having portions extendingaround the pins,saidbolts-liaving other portions projecting throughthere cesses and adapted to be secured toa casing, and a slushing ofmaterial embedding the hook bolts in the recesses and the pins 1" thesockets, substantially as described;

(3. A liningoi the character described, comprising blocks havingregistering recesses in their upper and lower'facesand socketsintersecting said recesses the sockets in the lower faces of the blocksbeing twice as (.ltfll as the socketsin the top faces of the. blocks,pins designed tobe inserted within said sockets ofjuthe'lower faces andto slide partly into the sockets of the upper faces, said pinsprojecting across the' registering recess s and holding devices adaptedto engage said pins, substantially as described.

In testimony whereof Iliave signed my name to this specification in thepresence of two subscribing witnesses.
